There's another solution that also works. I found it on this forum:

1、Go to the Build Path settings in the project properties.

2、Remove the JRE System Library

3、Add it back; Select "Add Library" and select the JRE System Library. The default worked for me.

This works because you have multiple classes in different jar files. Removing and re-adding the JRE lib will make the right classes be first
